->''"Unrequited love -- it's fantastic, because it never has to change, it never has to grow up, and it never has to die!"''
-->-- '''Vince''', ''QueerAsFolk''

If someone is in love unrequitedly really, really strongly and desperately, they might either [[LoveMakesYouEvil go]] [[LoveMakesYouCrazy bon]][[{{Yandere}} kers]] - or... follow a thought like "[[IfICantHaveYou if]] ''[[IfICantHaveYou you]]'' [[IfICantHaveYou don't]] ''[[IfICantHaveYou want to]]'' [[IfICantHaveYou have me, no one should]]!" and choose solitude or at least [[CelibateHero celibacy]] for the rest of their life.

Often, this trope is similar to 'pledging loyalty' to the beloved person and trying to be "loyal" regardless of what the person in question actually thinks of the character. Seeing (or at least feeling) the idea of loving another as some sort of betrayal. In that way, it is kind of a passive version of StalkerWithACrush, but with much less actively obsessive behaviour and more IWantMyBelovedToBeHappy involved.

If in the form of such a [[HeroicVow vow]], it often causes {{Inner Monologue}}s and moral conflicts, since the character must keep a balance between suppressing their feelings for the person (to prevent IfICantHaveYou and such) and abandoning their self-chosen duty.
Common reasons for choosing solitude because of unrequited love are not being able to ever love anyone else or still loving the certain person forever, although the love is unrequited.

Often, especially if the admirer and the subject of love formerly were JustFriends, this leads to extreme regret about the events that caused the love to be unrequited.

May be expressed with an ObsessionSong.

Not to confuse with: AllLoveIsUnrequited (due to similarity in names), {{Asexuality}} (a character fitting this trope is sometimes mistaken for asexual), StalkerWithACrush (it ''can'' lead to this, but does not necessarily do; because of [[TheUnfairSex a certain]] DoubleStandard subjects of this trope are easily considered to be this or to have such tendencies.)

Compare CelibateHero, SingleTargetSexuality, DoggedNiceGuy, IWantMyBelovedToBeHappy, LoveMakesYouCrazy, ForWantOfANail and MyGreatestFailure.

Contrast IfICantHaveYou, StalkerWithACrush, and LoveMakesYouEvil.

As a {{Love Trope|s}}, this tends to be of spoileriffic nature.

!!Examples

[[foldercontrol]]

[[folder: Anime And Manga ]]

* In ''Manga/{{Chobits}}'' it is stated that persocoms have a specific weakness to this. As [[RidiculouslyHumanRobot Ridiculously human robots]] they have a combination of emotional sensitivity and perfect recall that makes them highly susceptible to continual, ongoing traumatization long after the original event has passed; they literally ''can't'' let it go. One of the main characters becomes so depressed over her unrequited love situation that she loses her will to live and lapses into an irretrievable vegetative state.
* ''Anime/NeonGenesisEvangelion'' has a number of ''very'' {{egregious}} cases of this. As in, OmnicidalManiac levels of {{Egregious}}.
* ''FiveCentimetersPerSecond'' got backlash because the unrequited love ultimately did not last forever, with MakotoShinkai's intent to depict Takaki's maturation and his ability to move on, ending his obsessing over Akari.
* Nagi of ''Manga/HayateTheCombatButler'' may end up being this. Hayate has promised to always protect her, but hasn't shown much inclination of romantic affection for her. The UnwantedHarem hasn't ended though.
** Most of the girls in the show seem to be mixed between this and IWantMyBelovedToBeHappy, but Nagi's the only one of those to have gotten a [[ThePromise promise]] in the bargain.
* {{CLAMP}} is somewhat famous for this. It is even outright stated that every person is the same, no matter what world they are in. So, technically, no matter how many times they are reborn, their love will still be unrequited:
** ''Manga/CardcaptorSakura'' has Sonomi Daidouji who fell in love with her best friend since Kindergarten ([[spoiler:and is actually her [[KissingCousins cousin]]]]). Said friend got HappilyMarried and later died. While Sonomi did apparently marry a man and have a child with him, it didn't last and during the series she is single and still very much in love with Nadeshiko.
*** Hinted at with her daughter Tomoyo's love for Sakura, which lasts through the series, even after Sakura has hooked up with Syaoran. Even TsubasaReservoirChronicle's Tomoyo can't help obsessing over a Sakura she just met.
** ''XXXHolic'': [[spoiler: ''at least'' four people seem to nurse unrequited feelings for Watanuki, who himself is eternally waiting for Yuuko. The Zashiki Warashi maintains a friendly relationship with him but he doesn't seem to reciprocate her feelings, Himawari gets married but still seems to have lingering sentiment towards him (even her husband seems to like him), and Doumeki and Kohane marry each other, seemingly for the purpose of producing offspring who will keep him from being lonely.]]
* ''Anime/MillenniumActress'': Chiyoko, the title actress, fell in love with a fugitive artist/activist [[TheDulcineaEffect she met once as a teen]] and became an actress first to find him and later so he'd see her and find her. She eventually chose solitude and later admits [[spoiler: on her deathbed]] that [[WantingIsBetterThanHaving "she loves the chase more".]] The guy interviewing her also has a crush on her, but it's not known what he did after she disappeared from public life.
* ''Manga/LoveHina'': Even while they're [[spoiler: attending Keitaro's wedding to Naru, both Shinobu and Motoko remain in love with him]].
* ''Manga/AiYoriAoshi'': Even upon his marriage to Aoi, Mayu still hasn't given up on Kaoru and visits him once a month.

[[/folder]]

[[folder: Literature ]]

* In ''Literature/HarryPotter'', [[spoiler:Snape is in love with Lily through their childhood and Hogwarts years. Lily refused to associate herself with him after he humiliated her in public and ultimately chose Snape's school rival, James who had cleaned up his JerkJock act. They had a child named Harry, then they died and Harry grew up and to become a student of Snape, who treats Harry like shit because his dad is James... and because he's still angry and in love with Lily since childhood as he demonstrated with his Patronus causing [[TearJerker Dumbledore to tear up]]. "After all this time?" "Always."]]
** Also, [[OurGhostsAreDifferent Moaning Myrtle]] pops up in every other book to complain about how Harry never visits her. Then again, she's stuck as a thirteen(ish)-year-old girl forever, so it kind of fits.
* A played-with example in ''Literature/ThePrincessBride''. Buttercup swore "I shall never love again" after Westley was killed by pirates. She was going to marry Prince Humperdink, but she didn't love him, and it didn't matter to him that she didn't love him because he planned to kill her and frame Guilder.
* In ''Literature/{{Ivanhoe}}'', there is Rebecca's unrequited love for the titular Wilfred of Ivanhoe. There is a great deal of IWantMyBelovedToBeHappy involved.
* Baby Kochamma in ''Literature/TheGodOfSmallThings'' falls in love with an Irish priest in her teens and remains in love with him even when after he has died and she has reached old age.
* [[DivineComedy Dante Alighieri]] and Beatrice, not just in real life but even in his poetry.
* ''{{Glennkill}}'': [[spoiler:Beth. Also Ham]].
* Norwegian poet Creator/HenrikWergeland did the trope four times over, crossing into a {{stalker with a crush}}. The four girls combined led to his {{ideal woman}} or {{personal muse}}: Stella.
* In ''Literature/TheHunchbackOfNotreDame'', the book, Quasimodo falls in love with Esmeralda and [[IWantMyBelovedToBeHappy does selfless things for her for the rest of the book]] until they [[spoiler: [[DownerEnding both die]].]]
** Frollo, on the other hand, also falls in love with Esmeralda, obsessing over her, stalking at her, [[spoiler: attempting to kidnap her, and finally inducing her death.]] Understandably, his "love" was unrequited.
** Esmeralda herself is unrequitedly in love with Phoebus, who in the book is a jerk.
* Discussed by Anne Elliot in ''{{Persuasion}}'' where she claims it's a behavior particular to women, and that while men and women are equally capable of love, only women will keep loving after all hope is gone. [[spoiler: Turns out that she's wrong about that, and her true love Captain Wentworth was still carrying the torch for her even though he didn't think she cared about him.]]
* ASongOfIceAndFire has plenty. King Robert had always loved Lyanna Stark even after her death, but he never really knew her entirely. His wife Cersei was in love with Rhaegar Targaryen, whom Robert killed, but Rhaegar was really into Lyanna. Then there's Petyr Baelish, who has always been in love with Catelyn Stark, [[spoiler: and he started a massive war that tears the seven kingdoms apart, as his way of lashing out to the world when he lost her to Brandon Stark]].
